1675685 Spacer Sleeve | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta spacer sleeve is a machined spacing and alignment component used in the alternator mounting spacer sleeve. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it positions the alternator correctly on its mounting bolt so pulley alignment and bracket clamp load are maintained. Selection must be confirmed by OEM part number 1675685, the exact engine/product model, serial number and the installed assembly configuration.

🔌 Function

The spacer sleeve maintains the correct distance and alignment between the alternator mounting hardware and its bracket or belt guard, so that fastener clamping load is carried properly. Correct spacing keeps the alternator pulley in line with the drive belt.

⚠️ Common Signs of Failure

• Alternator or belt guard sitting out of alignment, causing belt tracking problems or rapid belt wear
• Loose or repeatedly loosening alternator mounting bolts
• Visible wear, elongation or scoring of the sleeve bore or ends
• Rattling or vibration noise from the alternator mounting area
• Corrosion or deformation preventing correct bolt torque from being achieved

🛠️ Service Notes

• A spacer sleeve sets a fixed length in the joint — never leave one out, shorten one, or substitute a stack of washers, or the clamping load and alignment will both be wrong
• Check that the sleeve is square and fully seated in its counterbore or recess before any fastener is tightened
• Discard a sleeve that is crushed, bell-mouthed, scored or corroded; a shortened sleeve lets the joint be over-clamped and the component distorted
• On sleeves in an oil circuit, make sure the bore is clear and that any seal running on the sleeve has a clean, unscored surface to work against
• Tighten the joint to the figure in the workshop manual for your engine, with the sleeve taking the clamping load rather than the component it protects
